I found the name of a second husband for a widow, but I can NOT find his dates of birth or death anywhere, not even on sites that are not known for their reliability. So I have to guess. I do have the date of the marriage, actually, so can I, say, put the year of the marriage and say "before this date" for the birth, and "after this date" for the death? That would certainly cover the bases, but it's not particularly useful. Suggestions? Thanks.
